About Duane Morris LLP

From its hub in Philadelphia to offices in Northern California to outposts in Singapore and Vietnam and back around to London, Duane Morris may be taking a Ferdinand Magellan approach to legal industry domination. The firm's specialties include litigation, corporate law, intellectual property, business reorganization and financial restructuring, employment and immigration, energy, health law, real estate and wealth planning.

Go West, More West, and Then a Little Farther West

Founded in 1904 by Russell Duane, a descendant of revolutionary polymath Benjamin Franklin, Duane Morris has exponentially grown in staff and locations from its early twentieth century beginnings. Under the leadership of Sheldon Bonovitz, who took the helm in 1998 when the firm held a legal team numbering around 200, Duane Morris more than tripled its attorneys on staff.

And in recent years, the firm has continued to strategically grow, especially by picking up lawyers from firms that haven't fared so well. In 2008, Duane Morris hired a team of construction lawyers from Thelen; the next year, it brought a group of attorneys on board from Wolf Block. Most recently, in 2012, Duane Morris hired 16 attorneys from Dewey & LeBoeuf, expanding its insurance, energy and technology practices in the process. And most recently, in 2013, the firm opened offices in Silicon Valley-where its attorneys will focus on patent litigation and patent prosecution, trademarks and copyrights, venture capital, private equity and related commercial litigation- and Muscat, Oman.

A Specimen of Study

Noting that Duane Morris tripled in size in just 12 years, Harvard Business Professor Boris Groysberg commissioned a study of the firm for his business students called "Duane Morris: Balancing Growth and Culture at a Law Firm," Groysberg found that, despite its rapid expansion, Duane Morris had maintained its "Quaker values" along with an "unusually narrow" spread between the highest and lowest partner compensations, according to the ABA Journal. The study also noted Duane Morris' practice of emphasizing lateral hires in its recruitment practices.

In 2013, Harvard Business School published its second case study of the firm, entitled "Collaborating for Growth: Duane Morris in a Turbulent Legal Sector." The case study examines the firm's success in maintaining its collaborative culture despite economic pressures impacting the global legal industry, as well as the firm's continuing expansion into new markets.
